Question

What is the SI unit of sound?​

Answer 1

Answer:

1. The SI unit of sound or more precisely frequency is hertz denoted by Hz.

2. The sound intensity is the sound of power per unit area that is the SI unit is watt per square meter W/m2.

3. SI Unit of sound intensity is decibel.

4. Sound intensity is defined as the sound power per unit area.

5. A decibel is a ratio of the observed amplitude, or intensity level to a reference, which is 0 dB.

Answer 2

• The SI unit of sound or additional exact frequency is hertz denoted by Hz.
• The sound intensity is that the sound of power per unit space that's the SI unit is watt per area unit W/m2.
• The pressure of the sound is that the distinction between the pressure caused by an acoustic wave and also the close pressure of the medium it's passing through.
• The SI unit of the pressure of the sound is understood as Pascal denoted by Pa.
• The term dB denoted by dB may be a relative unit of live wide employed in acoustics.
• Decibel is claimed to be an index unit accustomed to describing quantitative relation between the amount that's measured and a reference or the amount of threshold of zero dB.
• The quantitative relation is also the ability of sound, the pressure level or sound intensity, etc.
• A unit of sound is any unit that's acoustic or sound activity.
